Inspired by the British Pathfinder class it was deemed necessary to have equivalent ships, which led to this very innovative class. Oil firing was deemed to be an immediate success while the turbines had some teething problems, which led to a certain amount of scepticism in the Iberian navy.

Hi!

a) Interesting post.

b) The Santiago de Cubas are too large to be rated as CLs under the treaty (8,000ts maximum). Further more a 4x2 layout is too futuristic for 1917 (first unit laid down so they are designed 1915/16 most likely).

c) Too many classes to go into detail. Sometimes the changes between classes seems somewhat too optimistic.

d) I really like the idea of those scout cruisers.

e) Which classes/ships will you keep under the treaty? What about your tonnage limits?

f) I think you have "build" too many units. Beg your pardon, but I think 74 (if I got it right) cruisers sounds unrealistic for a mid-sized navy even if your draft covers a time frame from the 1890s to 1921. Just take a look at the Angola class. 12 units! Heck, somebody had to pay for them, man them, keep them running and pay for their crews!
I´m not sure what the others have but in the timeframe 1908-1920 "only" ~28 light cruisers (all below 6,000ts) were laid down for the RSAN.
So if you have another 10-12 years (before 190 40-50 cruisers total may sound realistic for Iberia. Or am I totally wrong? Should the RSAN have many more cruisers instead? Is 28 too low to be realistic?

Anyway, 74 cruisers total is even more than what the Germans build until 1918 !!!

Maybe in this reality, but how about our alternate reality ? Maybe it is not futuristic at all in that reality.

If you look at Japan, the Asama and Jakumo class ACs and the Tenryu and Kuma class CLs all have a 4x2 layout (Asama is 1910). The Nagara class even has a 3x3 layout. For me, it is how I like the gun layout. The one I truly like is 4x3 (Nagato's 4x3 layout was actually a suggestion of HoOmAn to replace the 16 inch guns). When I looked at the original data on Japanese warships, I noticed that quite a few had single guns. I don't like single guns (some of my ships have them though). When I simmed the ships, I didn't look at what is realistic for that time, I simmed it the way I like it.

Yep, but she´s a capital units and triples on BBs were already known - think Viribus Unitis or Nevada. Both classes laid down 1911. A year more or less for the introduction of heavy tripples doesn´t matter, though.


"When I looked at the original data on Japanese warships, I noticed that quite a few had single guns. I don't like single guns (some of my ships have them though)."

Until the plans to equipe german Emden with a 4x2 layout 1920/21 and the french Duguay-Trouin laid down 1922 _nobody_ used a 4x2 layout on cruisers. Further more, only a few cruisers carried twin turrets in those years anyway.
HMS Enterprise and her 15cm twin mount Type XVII forward introduced them to the RN light cruisers in 1926 while british CAs with that layout were first laid down 1924 (Kent-class), the advent of the german K-class first brought tripples on cruisers into the equation. The Italians were somewhat late, having the first 4x2 in 1928 on their Condottieri Class A and the Trentos in 1925. The IJN got their first light twins on the Yubari, 14cm guns but not in a 4x2 layout. The first IJN cruisers to have superfiring twin turrets were the Aobas 1924. Spain with the Canaris 1928 (a modified County anyway). Finally the USN. First twins on the Omahas 1918 but not superfiring. This honour belongs to the Pensacolas 1926...

So, beg your pardon, your designs are somewhat unrealistic...


"When I simmed the ships, I didn't look at what is realistic for that time, I simmed it the way I like it."

So you´re power-gaming where most others like Northman, Pengolodh, myself and some others try to do this as realistic as possible. When will you introduce your first nuke carrier? In 1942? Just kidding of course, but maybe you can try to get things more realistic, okay? Thanks very much....

It is okay to try to get the best - out of the technology available in those years.

Hey, more capital units! Wow... You´re really in trouble with the max number of hulls allowed under the treaty, eh?

"As to the number of cruisers, I have just about used the 360kton given to me by the Treaty and I have the Med, Atlantic and the Pacific to worry about - also I lost Diego Garcia due to lack of cruisers - not gonna happen again!"

Naja....

The tonnage comes with the treaty, okay, but this doesn´t mean you have to make full use of it, especially not for the time pre-treaty!

I´m not entirely sure but I think you even outbuild the British with those ~80 cruisers (this doesn´t count the ACs anyway), not only the Germans. Maybe even both together.
Really not bad for a mid-sized navy...

Sorry for saying this: You REALLY have to cut down your forces - all of them for the sake of it. Your fleet is totally out of the window. What you have posted so far is close to the strength of the RN, maybe even better in some categories. Unrealistic. You´re throwing the whole SIM out of balance.

Remeber what I once wrote: You´re not building your navy into a vacuum. If you like to do so, please do it on another board, in another simulation but not here. All you post here would have resulted in all our other fleets to be much larger.

I know my comments are not welcome, they´re not popular for sure but I will not accept you as a player if you continue to build up a number one navy. What you have here is not much better than 16inc posting he has 12 Hoods and 16 QEs. Sorry.

I tried to be diplomatic with my first post, giving you a hint that something may be wrong. You didn´t get the drift, oh no, instead you added even moer cruiser stuff!

Again: Even if you don´t keep all the stuff active under the treaty, it is too much by far.

I can accept your King being pro oil-burners earlier than others when you counter this on another field of naval architecture (carrier for example - none of them or cramped, weak and inadequate designs). This keeps the balance. ~80 cruisers do not. What will be next? 300 DDs? We had this before, ask 16inc about the reactions...

Grab your Whileys or any other cruiser book and read about cruiser developement. Count how mayn ships which navy had at the end of WW1 and start of WW2. Browse through all other players posts and try to get a picture of how many stuff we all have. Think about it and if you´ve cut your forces in half, we can discuss things again.

Believe me, I know how enthusiastic one can be about ones own designs. I would also like to have many more designs, showing my springstyle skills but I choosed to rate realismn higher than that.
Remember what you were told when you joined the SIM: Keep your feets on the floor. This is not the place to show everybody your dig is bigger than anyone´s else.

Last note: I hope you don´t take this post insulting. It is not meant this way. I just try to save our SIM. This is my priority no. 1 - everything else has to be sacrificed including new players if necessary.

I hope you got the point.

Still with a smile and lending you a hand if necessary,

HoOmAn - who is not God, not the moderator and not some kind of "realism police" even though he played this role more than once now.

some cruiser bench marks
--------------------------------------------------------------------------------
The omaha itself was ordered in 1916 and completed in 1920. She had twin turrets but they were not superfireing and she had casemate guns and she displaced 7050 tons standard. She was not very well protected. Everyone should keep in mind that the SIM is based on a slightly diferent world than we all know it in 1920 so we should all try to get on the same page and refrain from taking things personal. I myself have notice flaws in my design process as pertaining to my capital ships and its cost me a 14" armed battleship which almost certainly would not be the case with other navy's haveing a disadvantage in gun caliber to mine.
When we look at the size of world navy's we have to look at the overall political structure. Using Iberia as a start, it is a country that is more powerfull than historically and still retains some of its pre spanish american war territorys but not to many as to make the U.S. (a neutral country in our sim) significantly weaker. As a player of Iberia one must then look at the repercussions of comeing out of the spanish american war with more slightly favorable results as well (as it seems) avoiding the spanish civil war. In my opinion Iberia wouldn't be much larger in naval strength than a historical Italy with 4/5 battleships. When designing my navy i used a rule of thumb that for every battleship i have i will have three cruisers and five destroyers with a few extra for trade protection. Atlantis has 11 battleships, 22 cruisers (13 light,9 heavy) with at least 6 more on the way and roughly 56 destroyers with more on the way hopefully.
Lets just say Iberia has 4 battleships, that would mean that useing the 1:3:5 ratio Iberia would have 12 cruisers and at least 20 destroyers.

Grab your Whileys or any other cruiser book and read about cruiser developement. Count how mayn ships which navy had at the end of WW1 and start of WW2.




sorry, don't have one, and my stuff isn't at hand anyway - still in Germany


Quoted

Browse through all other players posts and try to get a picture of how many stuff we all have. Think about it and if you´ve cut your forces in half, we can discuss things again.




that is mostly gone :-(

cutting them in half isn't much of a prob - neither is getting away from the twin turrets. BTW, since we already agreed that the capital ships are ok, they will remain. also does anybody have suggestions for the conversion of cruisers to CVs? how does adding torpedo bulbs affect the block coefficient?

new cruiser list coming up ...

cheers

He´s not popular? Why is this?




Well, he is my chief negotiator and due to Treaty restrictions a lot of stuff witll have to go - 170 mm guns on light cruisers do not fit. Expensive the whole thing :-( I foresee a baaaad next posting for him.

Glad you don´t take it personal...
--------------------------------------------------------------------------------
Because I really like the design history, the concept, behind your designs. One can really see how things are crowing.

So don´t cut classes, cut numbers.

Btw, you´re not the only one with problems how to settle things down. Just look at my stuff. I have a pair of 28cm BCs in 1911 and a pair of 38cm BCs in 1920. I don´t call this a realistic design process.
But why is this? Simply because I completely _forgot_ a class of 35cm BCs in 1915/16! But all the stuff was posted and discussed so there was no chance to fix it. ( Now I have to live with the fact that my fleet lacks fast units. All I have are two 27kn BCs with 28cm guns!

So you have the chance to get maybe the most balanced and realistic fleet of us all because we´re discussing things before they are settled down for you.

Count of Riva?
--------------------------------------------------------------------------------
Hmmm...

I hope you´re not refering to me with "Count of Riva"?

The King of Riva, actually his name is Belgarion or just Garion for his wife and friends, is the leading character in the Belgariad-Saga written by David Eddings.

Ordinador Class 1903 – 1 ship 1903

Inspired by the British Pathfinder class it was deemed necessary to have equivalent

ships, which led to this very innovative class. Oil firing was deemed to be an

immediate success while the turbines had some teething problems, which led to a certain

amount of scepticism in the Iberian navy. Larger ships therefore were only equipped

with turbines uch later.

Well, looks like we´re getting somewhere.

That´s ~25 cruisers now, right? Plus your ACs of course. This sounds much better. To say the truth, it is less than I expected (around 35 cruisers).

So you really have a good cruiser force. Only one class is slightly above 8,000ts and has to be rated as CAs (Santiago de Cuba) but I guess that´s not a problem.

Do you have skipped the Hernan Cortez class?

well, not quite correct. nearly all carry 17 cm guns and therefore become CAs.

I am also accounting for losses in the Spanish American War.

Iberia will enter a cruiser buildup shortly ;-)

Do you plan to replace the 17 cm guns and replace them with smaller caliber guns (<15 cm) so they'll become CLs or do you keep them as CAs ?

well, that really depends on how many people are interested in my oil ;-) anybody interested in a trade treaty?

Also King of Riva, please contact me offlist, Iberia has a proposition for South Africa (and another one for Germany). email is graylion at sm-wg dot net.
